Yeah, not the one you are responding to, but I wouldn't define it as from scratch.

Personally, "know how to code" is basically having the logic an reasoning skills to read and understand and apply documentation for whatever subject you need for this job.

If you have never written a web app in your life, but you can follow next.js tutorials and customize them beyond the tutorials afterwards, then you're at the point where the only thing you need is more time or more docs based on what you need to do at work.
